About These Vintage Bernina Models:

The Bernina 117-950 series represents classic Bernina engineering from the mid-to-late 20th century. These machines are known for their robust construction, reliable performance, and longevity. Many of these vintage Bernina machines are still in active use today, cherished by sewers who appreciate their mechanical precision and straightforward operation.

Models like the 830, 840, 850, 930, 940, and 950 are particularly sought-after by vintage sewing machine enthusiasts. These machines were built to last generations, and with proper maintenance and the correct replacement parts, they continue to deliver excellent stitch quality decades after they were manufactured.

Why Metal Bobbins for Vintage Bernina:

Vintage Bernina machines were designed to use metal bobbins, and it's important to continue using metal rather than substituting plastic:

• Original Specification - These machines were engineered for metal bobbins
• Proper Weight - Metal provides the correct weight for optimal tension
• Durability - Metal withstands decades of use without cracking or warping
• Smooth Operation - Metal provides smoother rotation in vintage bobbin cases
• Heat Resistance - Won't deform from friction heat during extended sewing
• Precision Fit - Metal maintains dimensional accuracy over time
• Preserve Your Machine - Using correct bobbins helps maintain vintage machine performance

Different from Other Bernina Bobbins:

Bernina has used several different bobbin types over the years. This Part 330.026.030 is specifically for the vintage 117-950 series models and has different dimensions than other Bernina bobbins:

• Part 330.026.030: 21.8mm diameter, 7.3mm height, smooth core, no holes (for 117-950 series)
• Part 0115367000: 20.6mm diameter, 11.7mm height, diamond cut core, with holes (for 125-550QE series)
• Part 0060265000: Different size, diamond cut core, with holes (for Artista/Aurora series)

Always use the correct bobbin type for your specific Bernina model. Using the wrong bobbin size can cause tension problems, skipped stitches, or jamming.

Why Stock Extra Bobbins:

• Multiple Thread Colors - Keep different colors wound and ready for your projects
• Save Time - No need to unwind and rewind when changing thread colors
• Organize by Project - Wind bobbins for specific projects in advance
• Prevent Delays - Always have a backup when you're in the middle of a project

• Vintage Machine Care - Keep your classic Bernina running smoothly with quality parts
• Hard to Find - Stock up on these vintage-specific bobbins while available

Bobbin Care for Vintage Bernina Machines:

• Wind evenly - Use your Bernina's bobbin winder for smooth, even winding
• Don't overfill - Leave a small gap at the top to prevent jamming
• Check for burrs - Inspect metal bobbins regularly for rough edges that can snag thread
• Keep clean - Wipe off lint buildup periodically
• Store properly - Keep wound bobbins in a bobbin box to prevent thread tangling
• Match thread quality - Use quality thread appropriate for vintage machines
• Use winding slot - Engage the slot on the winding spindle for secure winding
• Replace when damaged - Don't use bobbins with dents, burrs, or damage
